Following the CSS examples, I have color styling working for all the area of the plot I care about *except* the grid line color. Thank you Uwe.

I'm using a dark canvas background, so I need to be able to change the grid lines from their default black to a light gray, and (preferably) control their transparency.

I've tried a number of different ways to get this working, but haven't been successful and didn't see it in the examples.

I need this last piece to give the user control of the plot style with CSS!

Please tell the me the grid lines can be styled with CSS.
